Status in “pulseaudio” package in Ubuntu: New Bug description: Binary package hint: pulseaudio First: note that this is not bug 446355, though it is similar. The message in the system log is: Oct 13 14:25:51 zest pulseaudio[3578]: alsa-util.c: Unable to set sw params: Too many open files Oct 13 14:25:51 zest pulseaudio[3578]: alsa-sink.c: Failed to set software parameters: Too many open files Infinitely, repeatedly, until the /var/log/syslog and /var/log/user.log files fill up the partition that they are on. I have had to clear my log files 3 times now in the past day because my root filesystem was full, which started breaking various things (like my postfix installation which gets my mail delivered directly to me). The log files are available on request privately, they contain information that I do not want published on the bug report, and due to their size, I cannot be sure to filter them and not accidentally remove anything relevant. There may be more in the log files than I have seen, simply because of the amount of stuff there. For anyone who requests the files, I'll email them: note that the log files are to 4 MB. However, they will expand to somewhere around 9 GB; compression on my system (4x 2.2 GHz 64-bit cores) took 300 minutes each, compressing with pbzip2. If you have a multiple-core system, decompression will go a lot more quickly if you use pbzip2 instead of bzip2 (and note also that compression took about 5 hours, I'd expect decompression to be similar). I will attached trimmed-down versions of these files as well, shortly after uploading the full log files. This bug causes denial of service of anything in /var or on /, so I am classifying this as a security bug.

Right, so you are using glitch-free. Let's see if we can narrow down whether it's linux or PA at issue, or possibly both.

I suppose I can find out, but if the problem is dependent on the kernel to be triggered, then this PA bug is a much larger bug than it would appear to be; PA should not have bugs able to be triggered by dropping in a newer kernel that fulfills the same interfaces.
